Background and objective <p>Physical activity is an effective non-pharmacological approach to enhance the well-being of individuals with schizophrenia. This study examined the impact of group sports-recreational activities on the quality of life of patients with schizophrenia.</p> Methodology <p>The statistical population of this semi-experimental study with a pretest–posttest design included 75 men with schizophrenia (mean age = 53.77 ± 4.74&#xa0;years) residing in the neuropsychological rehabilitation center of Susa city in southern Iran in 2024. Sixty participants were randomly selected and assigned to either an experimental group (n = 30) or a control group (n = 30). The experimental group engaged in group sports-recreational activities for 12&#xa0;weeks (three sessions per week, 20&#xa0;min per session). Data were collected using demographic questionnaire and the World Health Organization’s Quality of Life questionnaire, covering four subscales: physical health, psychological health, social relationships, and environmental health.</p> Findings <p>ANCOVA results, controlling for pretest scores, revealed significant differences between the groups in overall quality of life (F = 45.42, <i>P</i> = 0.001, η² = 0.61). Significant improvements were also observed in physical health (F = 12.26, <i>P</i> = 0.002, η² = 0.30), psychological health (F = 31.22, <i>P</i> = 0.001, η² = 0.52), social relationships (F = 12.20, <i>P</i> = 0.002, η² = 0.37), and environmental health (F = 10.80, <i>P</i> = 0.003, η² = 0.30) for the experimental group compared to the control group.</p> Conclusion <p>Group sports-recreational activities significantly improve the quality of life of patients with schizophrenia and should be included in rehabilitation programs.</p>
